Re: Best DOS video card?

I would take one with VESA VBE 2.0 - should be on S3 Virge and Trio64. But even that quality of VESA BIOS implementation may vary from manufacturer to manufacturer - better try with some problematic games and see. All this cards should have drivers for Win9X/NT/2K and shouldn't be problem to google …

Re: PCie-to PCI, PCI to ISA, # of slots multipliers - bridges, risers, backplanes, research, especially for DOS, WIP.

Thanks for your attention. Damn intel! I tracked chipset datasheets and the LDRQ was removed in 1xx series. The latest with LDRQ are H/P9x and X99. Do you have an idea how to overcome this issue with your FPGA/CPLD solution? Could they use some proprietary logic for this? I very doubt.. 🙁

Re: PCie-to PCI, PCI to ISA, # of slots multipliers - bridges, risers, backplanes, research, especially for DOS, WIP.

Where is the dedicated thread? AFAIK Win10 dropped support of ISA subsystem from the kernel so ISA card may not work there but it could work in DOS. The datasheet has better photo, from this I can read: IT8892E - PCIe to PCI Bridge F81866AD - LPC based superIO with 6x UART, LPT, FDC... F85226AD - …

Re: PCie-to PCI, PCI to ISA, # of slots multipliers - bridges, risers, backplanes, research, especially for DOS, WIP.

I just found a new review of MSI MB with PCI & ISA slots for LGA1151 platform (H110 chipset) https://www.tomshardware.com/news/spectras-new-lga1151-motherboard-1992-pci-slots It seem's nothing surprising, just another overpriced industrial MB. I wonder if ISA DMA would work there. I was not able to …

Re: PCie-to PCI, PCI to ISA, # of slots multipliers - bridges, risers, backplanes, research, especially for DOS, WIP.

I tried the AHCI driver with a PCIe JMB363-based card at first (my onboard SATA controller is already pretty densely populated), but wasn't very successful - the C drive was running in MS-DOS compatibility mode. It could be probably because your JMB363 card BIOS is configured in RAID mode instead …

Re: PCie-to PCI, PCI to ISA, # of slots multipliers - bridges, risers, backplanes, research, especially for DOS, WIP.

I'm talking about true DOS mode. And it's not just games - I was able to run LLSID and listen to some .sid tunes, something that wasn't possible with OPL3LPT for some reason. And yes, SFX doesn't work, as well as C-Media's official DOS drivers. Well, did you / can you try some YMF724/744 or Vortex …

Re: DOSBox 0.74 CPU Benchmark

Hi mothergoose729, I noticed that Ryzens have some way worse performance in Dosbox than intel on same frequency. Just could you make a quake test while set the CPU affinity for dosbox proccess to only one CPU core? And maybe same with disabled hyperthreading/SMT or how it's called on AMD in SETUP? …

Re: Yamaha YMF7x4 Guide

My YMF724 has a pair of jumpers that routes amplified or direct signal to output jack so I can select it. In your case I guess that front speaker output is amplified and rear output is direct.
